1. Executive Summary The Ventilation Rate Procedure as described in section 6 of ASHRAE 62.1 is used to calculate the required outdoor air supplied for the Miller Children s Hospital Pediatric Inpatient Addition. The has 7 air handling units supplying a constant air volume with heat coils for each of the spaces. The is a 4-story, 127,000 sq. ft. building attached to the existing Miller Children s Hospital. The building consists of 7 operating rooms, 27 patient rooms, a neonatal intensive care unit, physicians rooms, offices, conference rooms, a gift shop, and sanctuary. The mechanical penthouse is located on the roof, housing all 7 AHUs and supplies to each of the 4 levels through two centrally-located mechanical shafts. The ventilation rates have been determined using ASHRAE 62.1 for each space based on zone population, area, and function and then combined for each AHU. Using the mechanical drawings, the design airflows were calculated for each space and then combined for each AHU. The results can be seen in Table 1. Also an analysis of section 5 requirements of ASHRAE 62.1 reveals compliance in the area of systems and equipment to prevent re-entry of contaminated air and mold growth.

2. Building Overview The to Miller Children s Hospital is a 4-story, 127,000 sq. ft. facility. Operating rooms are located on the ground floor, which is actually below grade. The first floor consists of the main lobby with gift shop and sanctuary, conference and office spaces, and physicians rooms. The second floor houses the neonatal intensive care unit. Finally, the patient rooms are located on the third floor with mechanical penthouse on the roof above. The mechanical penthouse houses the 7 AHUs, which supply air to the 4 levels of the building through two centrally-located mechanical shafts. Figures 1 though 4 show the areas for each AHU. Figure 1: Ground Level AH-1 AH-2 AH-3 Technical Report 1 4
Figure 2: Level 1 AH-4 AH-5 Figure 3: Level 2 AH-6 Technical Report 1 5
Figure 4: Level 3 AH-7 The following figures illustrate the service of each AHU separated by levels. Notice in Figure 1: Ground Level that the operating rooms are served by a separate AHU (AHU-1). This unit uses a HEPA filtration system due to the critical nature of these spaces. The existing Miller Children s Hospital also went through renovations due to the addition. An existing AHU located on the ground level is used to serve the renovated spaces. For reasons discussed in the Mechanical Systems Summary, this unit (AHU-8 on the mechanical AHU schedule) was not included in the scope of this report but was included in the drawing package. 3. Mechanical Systems Summary The 7 AHUs discussed in the previous section supply a constant air volume with hot water reheat coils for each of the spaces. The building has 145 reheat coils with a 180 F entering water temperature. The reason for using a CAV system with reheat instead of a VAV system in the is because sensitive pressure differences must be maintained between certain spaces for safety to prevent the spread of hazardous air contaminants, ruling out the possibility of modulating air Technical Report 1 6
volume. The roof mechanical room houses (2) 2000 MBH boilers that supply hot water to AH-3 and reheat coils throughout the building. AH-3 is a 100% unit because it partially serves the operating room level of the building. Twenty-one fan coil units serve spaces throughout the building such as electrical rooms, elevator machine rooms, and telecom rooms. The entering water temperature is 45 F and is supplied from the chillers located in the central plant. The existing Miller Children s Hospital is considered a non-conforming building by California code. This means that although the existing central plant has enough capacity to serve the addition, the two systems had to be completely separated from one another. Therefore, the has its own central plant, which was part of a separate drawing package. Essentially, the two buildings are completely disconnected from one another. Because the existing AHU is located in Miller Children s Hospital and serves only Miller Children s Hospital, it was not included in the ASHRAE 62.1 analysis of this report. 4. Systems and Equipment Requirements Section 5 of ASHRAE 62.1 requires certain measures be taken to ensure that mechanical equipment be installed in such a way as to prevent mold growth and prevent re-entry of air contaminants back into the system. Table 5-1 in section 5.6 requires a minimum distance of 15 feet be maintained between air intakes and exhaust air under significantly contaminated exhaust conditions (See Appendix B). Figure 5 on the next page highlights this separation and after measuring the distances, the units do, in fact, comply with this standard. Section 5.15.2 requires that pipes, ducts, and other surfaces that are susceptible to condensation be insulated as to prevent mold growth. Located in the general notes on the first sheet of the mechanical drawings, the mechanical engineer specifies that these surfaces be insulated. This follows the ASHRAE standard. In addition to pipe insulation, the standard has strict specifications regarding drain pans. Also within the general notes are requirements to maintain certain sized drip pans as to comply with Technical Report 1 7
ASHRAE 62.1 section 5.11. This prevents the buildup of standing water and also prevents mold growth. Figure 5: Intake and Exhaust Figure 5 is a plan view of the mechanical roof penthouse and illustrates the relationship between intakes and exhausts for the 7 AHUs located on the roof of the. The intakes are highlighted in red and the exhausts are highlighted in green. All distancess according to section 5, Table 5-1 of ASHRAE 62.1 are within the separation distance for contaminated exhaust. 5. Ventilation Rate Assumptions ASHRAE 62.1 gives ventilation rates according to space occupancy, function, and floor area. These can be found in Table 6-1 of Standardd 62.1, although some spaces are not specifically definedd in this table, so certain assumptions have to be made in order to determine proper ventilation rates. Assumptions that were used for the ventilation rate calculations for the are as follows: Technical Report 1 8
Restrooms: 0.5 cfm/sf Locker Rooms: 0.5 cfm/sf 6. Ventilation Calculation Procedure The ventilation calculation procedure is thoroughly outlined in section 6 of ASHRAE Standard 62.1 and is summarized below. See Appendix B for ASHRAE 62.1 Tables. Breathing Zone Outdoor Airflow The design outdoor air required (Vbz) for the breathing zone is calculated using this equation: Vbz = Rp*Pz + Ra*Az Az is the zone area Pz is the zone population Rp is the outdoor airflow required per person (ASHRAE 62.1 Table 6-1) Ra is the outdoor airflow required per square foot (ASHRAE 62.1 Table 6-1) Zone Outdoor Airflow The design zone outdoor airflow (Voz) is the that must be provided to the zone by the AHU calculated using this equation: Voz = Vbz/Ez Vbz is the design outdoor air required Ez is the zone air distribution effectiveness (ASHRAE 62.1 Table 6-2), and is considered to be equal to 1.0 for ceiling supply of cool air Outdoor Air Intake For AHUs with 100% outdoor air, such as AH-3, the following equation should be used to calculate the outdoor air intake flow (Vot): Technical Report 1 9
Vot = all zones Voz For AHUs with multiple-zone recirculating systems, Vot must be calculated using the equation: Vot = Vou/Ev Vou is the uncorrected outdoor air intake, and for the purposes of this application, is considered to be equal to Vbz summed over all the zones for each AHU, since D, the occupant diversity, is equal to 1.0 Ev is the system ventilation efficiency (ASHRAE 62.1 Table 6-3) The zone primary outdoor air fraction (Zp) must be determined in order to apply values of Ev from Table 6-3 mentioned earlier. The equation for Zp is: Zp = Voz/Vpz Vpz is the zone primary airflow from the AHU including outdoor air and recirculated return air For values of Zp for which ASHRAE 62.1 Table 6-3 do not apply (values greater than 0.55), Appendix A must be used. Ev must then be calculated using zone ventilation efficiency (Evz) and the minimum value of these will be used for Ev. To calculate Evz, the following equation will be used: Evz = 1 + Xs Zd Xs is the average outdoor air fraction and is given as Vou/ Vpz Zd is the discharge outdoor air fraction and is given as Voz/Vdz For this calculation, the minimum Evz value that was calculated was 0.42. Therefore, the Ev value used is 0.42 for the spaces that do not apply to Table 6-3. This value seems reasonable and is probably an overestimate for calculating the quantities. The spaces include mostly restrooms, locker rooms, and smaller rooms for which there is no ventilation supplied directly to the space, but rather rely on infiltration from Technical Report 1 10
surrounding spaces to maintain proper ventilation. Once the outdoor air intake flow (Vot) is calculated for each space, and then summed, the values can then be compared with the supply air flow rates for each of the 7 AHUs. 7. Results As a result of the ventilation calculation procedure outlined in section 6, Table 2 shows that all 7 AHUs comply with the minimum requirements per ASHRAE Standard 62.1. Also illustrated in the table is the maximum primary outdoor air fraction (Zp) for each AHU, areas for each AHU, and the minimum required for the intake as calculated above. The unit capacity, which is the maximum amount of that can be supplied (assuming 100% ) is significantly greater than the minimum required by ASHRAE. One thing to note is that the minimum supplied for AHUs 1, 3, 4,and 6 will be sufficient to properly ventilate the spaces. AHUs 2, 5, and 7 will require slightly more than the minimum amount to properly ventilate the spaces.

The table shows that all seven AHUs comply with ASHRAE Standard 62.1. The unit capacity, which is the maximum amount of that can be supplied (assuming 100%) is significantly greater than the minimum required by ASHRAE. One observation is that the unit capacities are significantly larger than what is required for proper ventilation for Standard 62.1. A reason for this is that California abides by codes set forth by the Office of Statewide Health Planning and Development (OSHPD) for many aspects of the design and construction process in regards to hospitals and Technical Report 1 11
medical facilities. In some cases these codes could be stricter than ASHRAE standards, requiring more ventilation than ASHRAE Standard 62.1 requires. See Appendix A for detailed ventilation calculation results. Technical Report 1 12
